“…11-2-d). Such a closed alveolar basal part has been confirmed in other voles ( Gromov and Erbajeva 1995 ; Koenigswald and Kolfschoten 1996 ; Borodin 2009 ). In all of the molar samples showing these incipient root conditions, the enamel patterns of the occlusal surfaces do not commonly repeat those of the basal ends and both patterns do not correspond.…”

We evaluated the molars in Anderson’s red-backed vole (n = 114) from the Kii Peninsula of Honshu, Japan. Two of the specimens are considered extremely old aged based on their dimensions and on the loss of alveolar capsules of M2, and a third one is also old based on its strongly worn left M3 and M1. Of the former two individuals, one showed an incipient closure of re-entrant angles at its basal end, as estimated from the difference between the occlusal patterns of the occlusal and basal surfaces of the left M2. The latter individual also showed a complete closure of the basal end in the left M3. These patterns differ from incipient roots observed in other vole taxa but were similar to a previous example of incipient roots in Anderson’s red-backed vole. Therefore, we suggest that molar roots in this species form at an extremely late age or by strong wear. Root formation in molars is considered an important diagnostic character, as Eothenomys molars lack roots, while Craseomys molars develop roots at a late age. However, this dental character may be particularly difficult to assess in voles under natural conditions. Considering previous phylogenetic findings based on molecular analyses, Craseomys is the most appropriate genus for Anderson’s and other Asiatic red-backed voles.

“…In the M 1 of an individual of Ondatra zibethicus (Linnaeus, 1766) in which the roots are not yet expressed, the re-entrant angles in the alveolar basal part are completely closed ( Borodin 2009 : fig. 11-2-d).…”

“…Th is direction has been supported by the natural selection, because it morphologically provides a functionality in food consumption which was more eff ective than those for Cricetidae or optimal for Arvicolidae (Topachevsky, Skorik, 1992). Natural selection has gained an inertia action in all lineages of Arvicolidae, as manifested through the complication of the occlusal surface of their teeth due to appearance of additional enamel prisms on M3 as well as T4, 5 on m1 at the base of paraconid (Markova, 2014;Borodin, Markova, 2015). Th e adaptatiogenesis of Dicrostonyx is the peak of this process.…”

Phenomenon in the Evolution of Voles (Mammalia, Rodentia, Arvicolidae). Rekovets, L. I., Kovalchuk, О. М. -Th is paper presents analytical results of the study of adaptatiogenesis within the family Arvicolidae (Mammalia, Rodentia) based of morphological changes of the most functional characters of their masticatory apparatus -dental system -through time. Th e main directions of the morphological diff erentiation in parallel evolution of the arvicolid tooth type within the Cricetidae and Arvicolidae during late Miocene and Pliocene were identifi ed and substantiated. It is shown that such unique morphological structure as the arvicolid tooth type has provided a relatively high rate of evolution of voles and a wide range of their adaptive radiation, as well as has determined their taxonomic and ecological diversity. Th e optimality of the current state of this group and evaluation of evolutionary prospects of Arvicolidae were presented and substantiated here as a phenomenon in their evolution.

“…The identification of the small mammal was based on the best diagnostic elements available: for lagomorphs and rodents, mandibles, maxilla, and isolated teeth; for shrews, mandibles, and maxilla; for moles and bats, mandibles, maxilla, isolated teeth, and postcranial bones were analysed. The criteria for the identification of the material, the nomenclature for morphological descriptions, and the measurements taken follow Niethammer and Krapp (1978;1982), Nadachowski (1982), and Borodin and Markova (2015) for Rodentia; Laplana et al (2015) for Lagomorpha; and Niethammer and Krapp (1990) for Eulipothyphla; Sevilla García (1988) for Chiroptera. Comparison of the fossil specimens to the osteological collection of the University of Tübingen was also crucial for the identification.…”

In this paper, we analyse the fish and small mammal assemblages from the Middle Paleolithic horizons of Hohle Fels Cave to reconstruct the paleoclimatic and paleoenvironmental conditions faced by the Neanderthal groups who occupied the site. The fish assemblage indicates that the freshwater ecosystem around this site was characterized by a pre-mountain river system with the presence of permanent, oxygen-rich, and cold running waters. The results of the Habitat Weighting Method and the Bioclimatic Model applied to the small mammal assemblage, coupled with the new dates obtained for the Archaeological Horizon (AH) IX, allow us to identify two different climatic phases. One phase (AH X-XII) is more temperate possibly corresponding to the end of Marine Isotope Stage (MIS) 5; the other (AH VI-IX) is colder and more arid corresponding to the end of MIS 4 through the beginning of MIS 3. Open environments with a relatively stable forest component dominated the landscape during this part of the Middle Paleolithic. These two climatic phases appear to correspond to different levels of occupational intensity by Neanderthals, with higher occupational intensity during mild climatic periods and lower intensity during cold, arid periods. Our climatic reconstruction and recent absolute dating, together with the recovery of a complete leaf point near the top of AH X, have important implications for the cultural stratigraphy and cultural chronology of the region. Archaeologist have traditionally viewed leaf points as key artefacts of the Blattspitzengruppe, a cultural complex attributed to the end of Middle Paleolithic; however, this stratigraphic, climatic, and chronological context indicates the need to revise this interpretation.
